. i f RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 761,660, dated J 1111 '7, 1904. Application filed March 5, 1904. Serial No. 196,725. (No model.)

To (LM whom, t may concerns' Beit known that I, JOSEPH COLIN, a citize .f of the United States, residing at Ava, in the crease the general rigidity of the joints, and

for the above purpose the rails are of a special form, adapted for cooperation with a speciallydevised joint member by which same are connected.

For a nfull description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for elfecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic fea-- tures of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view showing the embodiment of the invention. Fig. 2 is a longitudinal vertical" sectional view through the rail-joint. Fig. 3 is a vertical transverse sectional view. Fig'. Lis a detail perspective view of the joint member connecting the rails, showing the adjacent rail ends spaced therefrom.

Corresponding and like parts are referred l to in the following description and indicated in all the views of the drawings by the same reference characters. v

Inthe drawings the rails are. designated l, and same comprise a head or ball 2, spaced webs 3, and basal flanges 4. rlhe spaced webs 3 of the rails diverge toward the basal anges 4, and thereby form a continuous groove extending longitudinally of the under side of the said rails. Because of the divergent relation of the spaced webs Sthe grooved portion 5 of each rail is of approximately triangular form, narrowing toward the upper portion thereof, as 'will be readily seen by reference to Figs. 1, A3, and 4. Each of the adjacent rails l is provided with an extension 6, projected from the head portion 2 thereof, which extension is received by a mortise or recess 7 in the corresponding portion of the adjacent rail end. The extension 6 being at the point of jointure of the rail ends is the means whereby a continuous bearing-surface at this point is secured. The jar and vibration consequent to the employment of the common type of rail is thus obviated. l

The means for joining or securing the meeting ends of the rails together consists of a joint member 8, which is of wedge form in cross-section and which virtually constitutes a wedge block. The joint member 8 is. disposed within the grooved portion 5 at the adjacent end portionsof the rails 1, and since this member is of wedge form, as set forth above, the same corresponds somewhat to the form of the grooved portion 5, as will be appreciated. The joint member 8 is provided with lateral openings 9, through which fastening-bolts 10 or the like pass, said bolts also passing through -corresponding openings formed in the web portions 3 of the rail ends. Projected upwardly from the upperl end portions of the joint member 8 are locking projections 11, which are received by recesses l2, formed in the ends of the rails, extending from the grooved portions thereof into the head portions of same. llhe projections l1. constitute interlocking means between the rails, which greatly reinforces the connection and subserves the rigidity thereof to a maximum degree. The projections 11 also cooperate, of

course, with the fastening-bolts 10 to secure the rail ends together. The wedge form of the joint member 8 is essentially advantageous in that therail end s are centered inthe relative disposition when receiving the pressure of the rolling-stock passingthereover. The wedge action thus obtained reduces the vibration in a manner apparent. The flanged basal portions 4 of the rail ends may be prop- IOO erijY secured to the adjacent ties in the practical use ot' the invention.

li'aving` thus described the invention, what is claimed as new isk 1. In a rail-joint, the combination of rails having the meeting,` end portions thereof provided upon the under sides with longitudinal grooves, a joint member disposed beneath the rails and received b v the grooved portions thereof, projections extending' upward from the end portions of the joint member and' interlocking with the rail ends, and transverse iastening's passed through the rail ends and the joint member securing same.

2. In a rail-joint, the combination of rails having diverged web portions providing a wedge-shaped groove upon the under side thereof, a wedge-shaped joint nienibor disposed beneath the end portions oi' the rails within the wedge-shaped grooved portions thereof, projections extended npwardljY lroni the end portions of the odge-shaped joint member, the rails bein;v provided with recesses to receive the projmftions aforesaid, and transverse ii'astenings passed through the raii ends and the joint member securing" saine together.

ln testimony whereof I aiiix in vsignaturo in presence of two witnesses.
